 Note: When using a Hugging Face model as a teacher, there is no scoring or cross-entropy filtering.
 
+#### CTranslate2
+
+The pipeline also supports CTranslate2 inference for HuggingFace models, which provides a considerable speedup.
+For that, simply add new boolean key:
+
+```yaml
+huggingface:
+    modelname: "facebook/nllb-200-distilled-1.3B"
+    lang_info: True
+    batch_size: 4096
+    lang_tags:
+      en: eng_Latn
+      ja: jpn_Jpan
+    ct2: True
+```
+
+We have done some benchmarking on 4 Nvidia Ampere A100 GPUs that shows CTranslate2 provides a 26x faster inference:

 ## Backward models
 
 Currently, only OPUS-MT models are available as backward models for scoring translations.
